Other options to intracorporeal morcellation include removing the uterus through a mini-laparotomy or morcellating the uterus inside a laparoscopic bag. da Vinci Gynecology Uterine leiomyomas are a common indication for power morcellation. Fewer than one out of 1000 women who undergo hysterectomy for leiomyomas will have an underlying malignancy. The SGO recognizes that currently there is no reliable method to differentiate benign from malignant leiomyomas (leiomyosarcomas or endometrial stromal sarcomas) before they are removed. Furthermore, these diseases offer an extremely poor prognosis even when specimens are removed intact. da Vinci Gynecology SGO Position Statement: Morcellation Age > 60 AA race: Two fold higher incidence Prolonged tamoxifen use, defined as five years or more Pelvic Irradiation Hereditary Leiomyomatosis and Renal Cell Carcinoma (HLRCC) syndrome- Rare autosomal dominant syndrome. Uterine sarcomas associated with HLRCC are often found in younger women Survivors of childhood retinoblastoma -Higher risk for sarcomas in general, including uterine sarcoma da Vinci Gynecology
